Abstract (en)
A differential gear includes a differential case (12) having a plurality of recesses (13) provided circumferentially at equal intervals, a plurality of pinions (14) and a pair of side gears (16) respectively disposed in the differential case (12), shafts (18,20) connected to the respective side gears (16) and a sleeve (42) supported by one shaft (20) shiftably in an axial direction thereof and unrotatably relative thereto and having a plurality of claws (43) capable of fitting in the recesses (13). A controlling device includes a cylinder unit (24) for operating the sleeve (42), a pressure sensor (26) for detecting the braking condition of a vehicle, a sensor (28) for detecting a steering angle and a controller (30) for receiving signals from both sensors (26,28) and controlling the cylinder unit (24) to limit the differential of the differential gear (10) when the vehicle is braked and turned with a steering angle exceeding a predetermined value.
